- Secure installation using hex drive socket for consistent torque application and knurled head for improved grip
- Industry compliance meeting RoHS 3 and REACH regulations for global manufacturing requirements
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw with Nylon Patch thread locker addresses critical challenges in precision assemblies where vibration resistance and positional accuracy are paramount. The Class 3A thread fit ensures precise engagement with mating components while the machined shoulder provides exact positioning for rotating parts in machinery, automation equipment, and electronic enclosures. The UNC coarse thread facilitates quicker assembly in production environments, and the hex drive socket with knurled head allows for secure tool engagement in confined spaces. Engineered for industrial applications requiring both corrosion resistance and mechanical reliability, this fastener maintains its locking capability across extreme temperature ranges from sub-zero conditions to elevated thermal environments.
Specification Summary & Compliance
This shoulder screw features Class 3A thread fit with UNC coarse thread specification (6-32 size), ensuring precise dimensional accuracy and reliable engagement. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards for environmental regulations. Manufacturing tolerances include shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005" for consistent performance in precision assemblies.
